Evaluate full SIMD Hamming distance performance #34

Open cmdevries opened 7 years ago

cmdevries commented 7 years ago

Use compiler intrinsics to try different SIMD implementations of Hamming distance for both exlusive or and population count

Can also try mixing SIMD Hamming distance on FPU + POPCNT which runs on the ALU to keep all execution units on the CPU busy.
